Hallo Erik,
ja das mit der Temp. anzeige im Bios hat sich Toshiba gespart 
Ich hab ab und zu mal den Fall das der Lüfter beim Booten auch nach Grub auf höchster stufe läuft, schaltet dann aber nicht runter (ist aber ehr selten der Fall). Meist läuft er nach grub auf ganz geringer Umdrehung.
Okay, hier mal der inhalt aus meiner sensors3.conf
libsensors configuration file
-----------------------------
This default configuration file only includes statements which do not
differ from one mainboard to the next. Only label, compute and set
statements for internal voltage and temperature sensors are included.
In general, local changes should not be added to this file, but rather
placed in custom configuration files located in /etc/sensors.d. This
approach makes further updates much easier.
Such custom configuration files for specific mainboards can be found at
